[Eesic] [ATLis] COMMENT ON: Hall C Moeller Quad Coil Repair/Replacement Work

Thu Aug 18 12:00:13 EDT 2011

Thanks for the Quick Meeting with Rick, "Neil"
I have 2 bpms that I need to disconnect electronics and cabling
to be out of your scope of work.
Everything after the 3C21 Girder needs disconnecting and removed
up to IBC3H04 but not including IBC3H04/IPM3H04H/IPM3H04V
